itext Styles: iText 5 versus iText 7
Remarks
Creating a document in which you have to switch between styles frequently tends to be tedious in iText 5. You need to create a lot of Chunk objects and you always have to make a trade-off between applying the styles directly to every new Chunk or creating a helper method that creates the Chunk for you.
What we fixed in iText 7:
It is now possible to chain methods. The setFont(), setFontSize(), addStyle(), and other methods all return the object on which they are invoked. Adding a Paragraph involving different styles can now be done in one line:
document.add(
new Paragraph()
.add("In this example, named ")
.add(new Text("HelloWorldStyles").addStyle(style))
.add(", we experiment with some text in ")
.add(new Text("code style").addStyle(style))
.add("."));
Using the Style object, you can now also apply different properties (font, font color, background color, font size,...) in one go with the addStyle() method.
